More specifically, the present invention is flexible cap for medical and dental needles so that the needle can be covered to prevent accidental needle sticking, to reduces the needle fear, and to reduce muscle pain during injection.
BACKGROUND OF THE INVENTION
Needle sticking is a global problem that many countries face as a public threat to health care. Many solutions have been proposed to prevent this complication, including various techniques for inserting syringes, burners, stands, etc. However, studies illustrate that this complication still exists as an inevitable problem in the medical staff despite these new achievements. Medical workers are exposed to this complication in high-risk groups. Sometimes a simple needle stick can lead to death. Research shows that medical workers put themselves at greater risk over time due to impatience, aging, and inattention to protective issues. However, global statistics indicate a high incidence of this complication despite the traditional methods and different devices. It still threatens many people, and every year, many people worldwide get involved and lose their lives. Many efforts have been made to eliminate the risk of needle sticking, which always involves the medical staff, and these efforts led to inventions in this -field. Some of them are related to the techniques and methods of needle recapping, the latest techniques of which can be referred to as the One-handed scoop technique. Research shows that medical and dental students and young dentists and physicians are less prone to this problem due to their greater caution than dentists with more experience. Over time, they put themselves at greater risk due to boredom, old age, and inattention to protective issues.
Moreover, such methods are often ineffective and not a suitable method of prevention.
Current advancement within the medical and dental industry is explained in relation to the following patents. Patent CN209951404U explains a sharp medical tool basket that is made to help cut sharp tools. Patent CN210078491U explains a device for making a protective syringe coating. However, the protective syringe coating device is generally expensive and often do not have much efficiency, and besides, infection control of these devices is not easy. Patent US20200069885A1 explains a safe syringe that is efficient. However, the safe syringe explained in US20200069885A1 has to change the syringe infrastructure and cannot be used for metal dental syringes.
Therefore, the cost per syringe is much higher than conventional needles and syringes.
It is there an objective of the present invention to provide a flexible cap for medical and dental needles. More specifically, the present invention is able to selectively lock the needle within so that accidental needle sticking can be avoided. The present invention also able to effectively reduce the patient's fear and anxiety, give them a sense of calm, and make the injection more enjoyable during an injection process.
